Versuchsvorschrift

A round-bottomed flask was charged with 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (210 mg, 0.48 mmol) and 1-oxazol-2-yl-ethylamine dihydrochloride (198 mg, 0.86 mmol). DMF (2.2 ml) was added followed by N,N-diisopropylethylamine (0.55 ml, 3.15 mmol) and HATU (199 mg, 0.52 mmol). The light yellow solution was stirred at room temperature overnight. Water was added and the resulting suspension was filtered. The solid was washed with water and petroleum ether then dried under high vacuum to afford 248 mg (97%) of 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (1-oxazol-2-yl-ethyl)-amide as a light yellow powder.
